Antioxidants Profiling of By-Products from Eucalyptus Greenboards Manufacture.

Three different by-products from the wood industry have been exhaustively characterized to find compounds with antioxidant properties. The industrial process to manufacture greenboards is distinguished by using just wood and water, which converts the generated by-products in a highly attractive source of bioactive compounds that are originally in the raw material. The studied by-products were: the screw water, derived from the washing of the wood chips; the condensates, obtained after the evaporation and further condensation of the screw water; and finally, the concentrate of eucalyptus.
